“…The use of millimetre wave (mmWave) technology is expected to have a major impact on 5G networks (Roh et al 2014), and will further increase the complexity of 5G base station antennas. A scarcity of spectrum available for cellular communications at microwave frequencies combined with the need to provide increased data capacity has led researchers to look to mmWave bands.…”

“…Due to the small wavelengths at mmWave bands it is possible to design high-gain arrays using a physically small aperture. Recent studies published by researchers from Samsung reported a mmWave prototype communications system operating at 28 GHz with more than 500 MHz of bandwidth (Roh et al 2014). This system provided both indoor and outdoor coverage over a radius of a few hundred metres and was able to support data rates greater than 500 Mb/s.…”

SummaryCellular mobile networks have enabled ubiquitous communications and largely changed the way we live and work. At the same time, the network itself has been undergoing significant changes in the process of meeting our ever increasing demands on data rate and quality of service. In this article, we show the path of the evolution in both standards and techniques, and provide our vision for the future of the cellular networks. We review the evolution of international standards for cellular mobile networks in the last two decades, describe how the network layout has been migrating from rigid cellular architecture to random and dense small cells, and provide an indepth discussion on potential enabling techniques for the next generation (5G) cellular networks, particularly massive MIMO and multiband base-station antennas.

“…Among the various requirements for next-generation wireless systems (for both cellular and access), achieving multigigabit/s data rates is one of key requirements, and millimeterwave (mmWave) wireless technologies have been mainly considered to achieve this goal where the considering mmWave frequencies are 28 GHz [1], 38 GHz (or 39 GHz) [2,3], 60 GHz [4], and 73 GHz [5] bands. The use of mmWave bands for next-generation wireless systems could offer ultra-wideband spectrum availability and increased channel capacity.…”

This paper provides practical 60 GHz link budget estimation results with IEEE 802.11ad standard-defined parameters and 60 GHz specific attenuation factors. In addition, the parameters from currently developing modular antenna arrays (MAAs) are adopted for estimating the actual link budgets of our 60 GHz integrated MAA platforms. Based on the practical link budget analysis results, we can estimate fundamental limits in terms of achievable data rates over 60 GHz millimeter-wave wireless links.

“…Several initiatives and proposal are ongoing to expand the current cellular bandwidth within the microwave frequency range [11], which is not enough to achieve the capacities needed by 5G systems and the devices connected to the Internet of Things (IoT). There is a vast amount of spectrum available at the mm-wave frequency bands, ranging from 3 to 300 GHz [11,17,44,46,58]; therefore, mm-wave frequency bands are being proposed to be used in 5G cellular networks.…”

Wireless technologies are an essential communication means that transform a branched localized fixed meshwork into a ubiquitous disconnected network. A clear trend shows that cells are becoming smaller, homogeneously distributed, operating at higher carrier frequencies, and more energy conscious. This points toward wireless picocell systems that implement millimeter-wave (mm-wave) modulation. In this work various techniques are proposed, which are oriented to specific traits of the 60-GHz mm-wave band. Two techniques oriented to solve physical and data-link layer issues are proposed. Single carrier frequency division multiple access (SC-FDMA) is proposed as the technology to be implemented at the physical layer, and a variable slot time multiplexing access technique, called variable slot time-time division multiple access (VST-TDMA), with a conscious energy-conservation protocol, is proposed for the data-link (MAC) layer. SC-FDMA with pulse shaping is implemented to minimize the peak-to-average power ratio of the system, which reduces energy consumption. The multiplexing access technique takes advantage of the reduced cell size by multiplexing data in the time domain, this allows the reduced number of users to utilize the entire available bandwidth. Incorporated into the access protocol is the option of energy pacing or even self-sustainability if an energy harvesting device is present. Self-sustainability can be achieved at the cost off throughput, some techniques are discussed to relieve this trade-off condition. Also, a thorough discussion is included on battery energy depletion, even with an energy harvesting device present, to further increase the through- put performance. Since using SC-FDMA reduces the energy consumption, it enables VST-TDMA to operate at higher speeds under self-sustainability mode. Overall the proposed set of solutions showed independently significant improvements to the system. It is also discussed how these techniques coalesce conveniently by working in unison, improving the energy efficiency and throughput capabilities of 60-GHz systems.Keywords 60 GHz · Energy self-sustainability · Millimeter-wave · Peak-to-average power ratio (PAPR) · Single carrier frequency division multiple access (SC-FDMA) · Variable slot time-time division multiple access (VST-TDMA)
